Do you like it if someone talks to you? I hate it, I like it it quite all the time. At least they should lear to follow the rule of conversation which says 'a conversation must comprise of 80% of listening and 20% of talking' The world would be better place if everyone stood by it. Sometimes it's so bad I wish humans could'nt speak, wish they communicated with sign language (haa :) the world would be so quite). Unnecessary conversation at a boring junction of time can tick off anyone, don't you think?
